Have a set of 17g BM and 16g BM and am having a hard time deciding on which to use as a cross w/ Pacific Tough Gut 16g. The Pacific rep in town is wanting me to try the tough gut/polyforce hybrid, but the stiffness rating of 320 scares me a bit:-? Those who are using the BM as a cross--what gauge are using? I am coming from Pacific Classic/Topspin CybeRed 17g. The Topspin is nice, but outside the sweetspot it can be a bit jarring. Def not as soft as CyberBlue or even CF for that matter. Thanks in advance for the input!
